The PCM5242 is a monolithic CMOS integrated circuit that includes a stereo digital-to-analog converter and additional support circuitry in a small QFN package. The PCM5242 uses the latest generation of TI's advanced segment-DAC architecture to achieve excellent dynamic performance and improved tolerance to clock jitter.

The PCM5242 integrates a fully programmable miniDSP core, allowing developers to integrate filters, dynamic range controls, custom interpolators and other differentiating features to their products.

The PCM5242 provides 4.2VRMS ground-centered differential outputs, allowing designers to eliminate DC blocking capacitors on the output, as well as external muting circuits traditionally associated with single supply line drivers.

The integrated PLL on the device removes the requirement for a system clock (commonly known as master clock), allowing a 3-wire I 2 S connection and reducing system EMI.

PCM5242RHBR Pinout

Package: 32-VFQFN Exposed Pad

Notes

WARNING: Pin numbering could not be determined. The provided datasheet section contains control mode information and references pin assignments, but does NOT include:

• A pin assignment table with pin numbers
• A pin diagram or package drawing image
• Any explicit mapping of pin names to pin numbers

To extract the complete PCM5242RHBR pinout, the following are required:

1. A pin configuration table (Table 6.2 or similar) with Pin Number and Pin Name columns
2. A package diagram image showing the 32-pin VFQFN layout with numbered pins
3. Pin descriptions and functional assignments

Recommendation: Provide the full Section 6.2 table and any associated pin diagram images from the PCM5242 datasheet.

All specifications at TA = 25°C, AVDD = CPVDD = DVDD = 3.3V, fS = 48kHz, system clock = 512fS and 24-bit data unless otherwise noted.

Differential outputs DAC's are regularly used where higher performance is required from them compared to single ended output DACs. They offer twice as much output voltage for the same power supply, along with noise cancelling effect of differential signaling. The PCM5242 makes an ideal front end for both analog input speaker amplifiers and headphone amplifiers with its higher voltage differential output and low noise floor.
